Clear Dock does work in Panther, I just installed it and I'm getting a transparent dock. However, what I liked about Transparent dock is the ability to change the font size of the dock. Can't wait for an update. But Clear Dock works for the time being.

ClearDock 1.2.4 is supposedly already Panther comliant according to their Panther update page. Versions of FruitMenu, WSX, and Xounds are all coming this month for Panther. Also included in WSX will be some bug fixes with the MiP feature....
